ItemLimiter

---

Three systems, one plugin

Each item in items.yml picks any mix of the three. Leave out what you don't need.

Also supported

• Acquisition caps → per-player and global limits, persisted across restarts
• Enchantment rules → max level + per-source blocking (anvil, table, loot, trading…)
• Potion rules → level + duration caps, covers splash / lingering / long / strong in one entry
• World restrictions → whitelist or blacklist per item
• Exceptions → per-rule bypass via permission or item descriptor (named items, custom model data, external plugin items)
• MySQL / SQLite → pick either, data survives restarts
• MiniMessage → gradients, hex, legacy codes, PlaceholderAPI
• Client cooldown bar → via optional PacketEvents
